What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00079 | $0.03871 |
| Opus 5 | $0.00039 | $0.01936 |
| Sonnet 5 | $0.00016 | $0.00774 |
| Haiku 4.5 | $0.00008 | $0.00387 |
Grade A, and why
heatmap-visualization scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Heatmap Visualization Skill
Purpose
Generate interactive heatmap visualizations from Microsoft Sentinel data using the Sentinel Heatmap MCP App. Heatmaps display aggregated data in a row/column grid with color-coded intensity, ideal for identifying patterns across time periods, comparing entities, or spotting anomalies.

Quick Start
Minimal Heatmap (3 Steps)
# 1. Query Sentinel for aggregated data
mcp_sentinel-data_query_lake({
"query": "SigninLogs | where TimeGenerated > ago(24h) | summarize value = count() by row = AppDisplayName, column = format_datetime(bin(TimeGenerated, 1h), 'HH:mm') | project row, column, value"
})
# 2. Display heatmap
mcp_sentinel-heat_show-signin-heatmap({
"data": [<query results>],
"title": "Sign-Ins by Application (Last 24h)",
"rowLabel": "Application",
"colLabel": "Hour (UTC)",
"valueLabel": "Sign-ins",
"colorScale": "green-red"
})

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

heatmap-visualization is a skill published in the GitHub repository SCStelz/security-investigator (244 stars, last pushed 3d ago), licensed MIT. It adds 79 tokens to every session and 3,871 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
